Several technologies exist for encryption, such as symmetric key cryptography and asymmetric key cryptography.
目前有几种加密技术如对称密钥密码系统和非对称密钥密码系统。
Asymmetric cryptography: Public-key cryptography (these two terms are synonyms).
不对称加密：公钥加密(这两个术语是同义词)。
The transmitted data is encrypted using public key (asymmetric) cryptography so that only the holder of the corresponding private key can decrypt the data.
传递的数据使用公钥(非对称)加密算法加密，所以只有对应私钥的持有者才能解密数据。
Compared with other asymmetric cryptography, ECC provides higher strength per bit, makes faster computation and requires shorter key length.
同其它非对称加密体制相比，ECC被认为能提供更高的加密强度，并具有更快的执行速度和更小的密钥长度。
The two main competing cryptography schemes are known as the secret-key (symmetric) system and the public-key (asymmetric) system.
现有两种主要的、相互竞争着的密码术，被称作秘钥（即对称）系统和明钥（即不对称）系统。
Public Key and Asymmetric - Public-key cryptography uses a pair of keys, one that is designated the private key and kept secret, the other key is called the public key and is generally made available.
公钥和非对称公钥密码学使用一对密钥，其中的一个定义为私钥并加密存放，另外一个被称为公钥，通常无须加密。
Asymmetric keys are used in public-key cryptography, which USES two keys, a public key and a private key, which are related mathematically.
非对称密钥用于公钥加密，公钥加密使用两个密钥，即在数学上相关的一个公钥和一个私钥。
Asymmetric keys are used in public-key cryptography, which USES two keys, a public key and a private key, which are related mathematically.
非对称密钥用于公钥加密，公钥加密使用两个密钥，即在数学上相关的一个公钥和一个私钥。
